- Electronics in aerospace applications such as satellites and aircraft are subjected to high levels of radiation from high-energy particles (heavy ions). ST proposes a large portfolio of products specifically designed, packaged, tested and qualified so they comply with the standards for aerospace defined by the qualifying agencies.
- ST has supported European aerospace applications since 1977, being qualified by the ESA (European Space Agency) since the agency's inception. Today, ST has broadened its efforts by qualifying products according to the American QML-V standard (of the US DLA - Defense Logistics Agency), and in accordance with RHA certification (Radiation Hardness Assurance).
- ST offers a wide aerospace product range, from diodes and transistors to A/D converters and voltage regulators, through its traditional logic circuits range. It is actively working on further expanding this offer.
